Occupational allergies and respiratory health issues are an increasing concern across various industries, significantly impacting worker productivity, well-being and long-term health outcomes. These health problems are primarily triggered by exposure to airborne allergens such as pollen, mold and chemical irritants commonly found in workplace environments. Climate change exacerbates these issues by altering environmental conditions that influence allergen distribution and intensity. Rising temperatures, increased humidity, worsening air pollution and extreme weather events contribute to prolonged pollen seasons, greater mold proliferation, increased volatile organic compound (VOC) emissions and heightened respiratory health risks among workers. VOCs are chemical pollutants emitted from a range of indoor and outdoor sources, further aggravating air quality in workplace environments.

An emerging concern is the relationship between climate change and thunderstorm asthma, a phenomenon where allergens are dispersed during thunderstorms, leading to acute asthma events. Ongoing research continues to examine how environmental changes contribute to the frequency and intensity of asthma-related health issues, particularly in occupational settings.

Both outdoor and indoor workers face distinct challenges due to climate-driven changes in allergen exposure. Agricultural, forestry and construction workers are especially vulnerable to longer pollen seasons and higher concentrations of air pollutants. In contrast, office, healthcare and industrial workers face increased exposure to indoor allergens due to poor ventilation, rising VOC concentrations and other environmental stressors. Low-income workers, older adults and those in developing countries face disproportionate risks due to limited access to healthcare and protective measures.

This viewpoint article explores the relationship between climate change and occupational respiratory allergies, emphasizing the need for effective workplace adaptation strategies such as improving ventilation systems, using air filtration technology and creating allergen-free zones. It also examines the socioeconomic barriers to implementing these measures, mental health impacts of occupational allergies (including stress, anxiety and absenteeism) and the emergence of new allergens due to changing environmental conditions. Furthermore, technological solutions such as AI-driven air quality monitoring systems and wearable sensors hold promise in mitigating allergen exposure by providing real-time data, enabling proactive health measures and supporting policy development to protect worker health. Addressing these challenges is critical to ensuring workers’ health, well-being and productivity in the face of ongoing climate change.

BACKGROUND: Exposure to environmental noise may have a negative impact on a population's mental health. We estimated the prevalence of exposure perception to high environmental noise in the Valencian Community, a region on the Mediterranean coast of Spain, and analysed its association with poor mental health risk, adjusting for demographic, socioeconomic and health status variables. METHODS: Cross-sectional study based on a sample of 5.485 subjects, aged 15 or above, of the 2016 Valencian Community Health Survey. The risk of poor mental health was assessed via Goldberg's questionnaire, a highly standardized self-reported questionnaire designed to screen for general psychological distress in the general population. Noise perception were determined in the home environment based on individuals' responses to the Valencian Survey question about external noise problems. Sociodemographic variables, such as sex, age, level of education, or country of birth, and health variables, such as self-perceived health, or chronic diseases, were also considered. Logistic regression was used to estimate the Odds Ratios and confidence intervals of association between variables according to sex. RESULTS: The prevalence of poor mental health was 26.2% [n = 2665; 95% CI: 24.5-27.9] in men and 33.6% [n = 2820; 95% CI: 31.9-35.3] in women. A total of 7.8% [n = 5485; 95% CI: 6.8-8.8] presented exposure to high noise perception, with no differences according to sex. Being at risk of poor mental health was significantly associated (p < 0.05) with high noise perception after adjusting for the rest of the variables (OR: 2.16 [95% CI: 1.46-3.19] in men; 2.46 [95% CI: 1.72-3.50] in women). CONCLUSIONS Although the prevalence of exposure perception to high noise was not very high, population subgroups presenting high values were detected. High noise perception was related to the risk of poor mental health, regardless of other variables. Poor mental health risk was associated with exposure perception to high noise, other socioeconomic determinants, and health status. Improving noise exposure conditions could reduce the risk of poor mental health.

INTRODUCTION

Rabies is a public health concern in the Philippines, where gaps in animal bite prevention and control persist despite national mandates. The One Health approach is a framework which recognizes the interconnectedness of human, animal, and environmental health. Although the Anti-Rabies Act of 2007 aligns with the One Health strategies, its implementation at the local level faced many challenges in coordination, delivery of service, and program sustainability.

This study aimed to determine the factors influencing the acceptability of One Health approach among key stakeholders as a strategy in the prevention and control of animal bites and rabies in the municipality of Alaminos, Laguna.

A qualitative Grounded Theory design was used in the study. Eleven key informants from the provincial, municipal, and barangay levels were interviewed.

Thematic analysis of key informants’ responses revealed that, despite limited awareness of the One Health approach, multi-sectoral coordination aids program implementation, although operational gaps remain. Fragmented program delivery, lack of formal training and certification, unclear roles, poor communication, inactive task forces, outdated ordinances, weak enforcement, limited community engagement, and low prioritization of rabies prevention collectively hinder effective implementation.

The study highlights the complex challenges of implementing the One Health approach for animal bites and rabies control in rural communities. Effective implementation requires strengthened stakeholder capacity-building and training, enhanced community engagement, improved access to veterinary services, reinforced intersectoral coordination and policy enforcement through revitalized task forces, and ongoing monitoring of progress through vaccination coverage and incidence data.

COVID-19, caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), was first identified in Wuhan, China in late 2019. Rapidly spreading worldwide, it was declared a pandemic by the World Health Organization (WHO) in early 2020 [1]. Various mitigation strategies, such as physical distancing, travel restrictions, and other public health protocols, were enforced globally to curb virus transmission [2,3]. However, these measures also disrupted daily life, work environments, and public health systems, posing significant challenges in balancing virus prevention and continuation of economic activity [4]. This paper aimed to highlight key lessons from the Third Environmental and Occupational Health (EOH) Forum on public health emergency response as demonstrated by selected Asian countries. Proceedings from the forum were reviewed and analyzed, arriving at the following lessons and themes: proactive and strategic public health interventions, leadership and governance, community participation, policy adjustments, technological integration and innovation, and balancing health and economic activities. The forum, themed “Environmental and Occupational Health Initiatives During the COVID-19 Pandemic,” was held virtually in November 2020 [5]. Understanding environmental and occupational health interventions as well as the themes of strategies by Asian countries, provides valuable insights into early pandemic management and contributes to a repository of knowledge that can be adapted and applied globally, enhancing the overall effectiveness of pandemic responses.

Climate change is the great health challenge for human beings in the 21^st century. Air pollution is also an important public health problem worldwide. China announced the climate commitment to achieve carbon peaking by 2030 and carbon neutrality by 2060. Achieving these goals would not only have far-reaching effects on air pollution control and climate change, but also improve the population health in China. Air pollution and climate change epidemiology are important aspects of environmental epidemiology. In this paper, we discuss the current status and future development of epidemiological research of air pollution and climate change in the context of achieving carbon peaking and carbon neutrality goals to provide ideas and suggestions for environmental and health studies in the future.

Even after two years, the COVID-19 pandemic still disrupts public activities and services as it exposes vulnerabilities among the population and negatively impacts environmental conditions. The crisis also impeded global progress toward achieving Sustainable Development Goals (SDG). The Fourth Environmental and Occupational Health (EOH) Forum held virtually on November 25 to 26, 2021 provided a venue for learning about local and international COVID-19 responses to help prepare for the next global crisis. Through the systems thinking approach, the discussions prioritized analyses of leadership and governance, financing, human resource, technologies, information management, and service delivery. These analyses focused on community and/or workplace programs and services linked to air quality, waste management, psychosocial wellness, and COVID-19 vaccination. The forum amplified calls for climate actions and public health improvement and emphasized the significance of a collaborative, evidence-based, integrated public health response to a crisis underscoring the apparent interdependence of the SDGs.

With the progress of globalization and the improvement of transportation, a public health emergency can spread across country's boundary in a short period of time from its original place to other areas or regions, posing public health threatens. Public health emergencies not only affect human-animal/plant-environmental health, but also have long-term implications for social development, so the public health emergency response has gone beyond general public health and requires an integrated and comprehensive One Health approach. This paper analyzes the problems and shortcomings of China's current public health emergency response system in a view of One Health and put forward the recommendations based on One Health concept on integrality, collaboration, development and sustainability of public health emergency response. These recommendations can be used as reference to further optimize the response system of public health emergencies in China.

BACKGROUND: The Hokkaido Study on Environment and Children's Health is an ongoing study consisting of two birth cohorts of different population sizes: the Sapporo cohort and the Hokkaido cohort. Our primary objectives are to (1) examine the effects that low-level environmental chemical exposures have on birth outcomes, including birth defects and growth retardation; (2) follow the development of allergies, infectious diseases, and neurobehavioral developmental disorders, as well as perform a longitudinal observation of child development; (3) identify high-risk groups based on genetic susceptibility to environmental chemicals; and (4) identify the additive effects of various chemicals, including tobacco. METHODS: The purpose of this report is to provide an update on the progress of the Hokkaido Study, summarize recent results, and suggest future directions. In particular, this report provides the latest details from questionnaire surveys, face-to-face examinations, and a collection of biological specimens from children and measurements of their chemical exposures. RESULTS: The latest findings indicate different risk factors of parental characteristics on birth outcomes and the mediating effect between socioeconomic status and children that are small for the gestational age. Maternal serum folate was not associated with birth defects. Prenatal chemical exposure and smoking were associated with birth size and growth, as well as cord blood biomarkers, such as adiponectin, leptin, thyroid, and reproductive hormones. We also found significant associations between the chemical levels and neuro development, asthma, and allergies. CONCLUSIONS Chemical exposure to children can occur both before and after birth. Longer follow-up for children is crucial in birth cohort studies to reinforce the Developmental Origins of Health and Disease hypothesis. In contrast, considering shifts in the exposure levels due to regulation is also essential, which may also change the association to health outcomes. This study found that individual susceptibility to adverse health effects depends on the genotype. Epigenome modification of DNA methylation was also discovered, indicating the necessity of examining molecular biology perspectives. International collaborations can add a new dimension to the current knowledge and provide novel discoveries in the future.
